Is there anything I can do to make KDE run faster on MD's or is this just a casualty of running diskless MD? I can watch paint peel faster than thinks move in KDE.

Is it the processing that is slow or the video re-render when putting the orbiter on screen? And are you using Alpha blending or overlay? Because those have different requirements and could cause slowdown in different ways with how the cards are accessed and such?

I am using an Atom MD and for giggles started KDE, when TSCHAK mentioned snail speed. Well, I did not have snail speed, everything worked as expected, as it works on another Atom powered stand alone PC.

According to top, "mythcommflag" is absolutely molesting the resources when I go into KDE desktop, CPU usage does not drop below 99, and often goes above 100, even once the desktop is apparently loaded up. This is 1004. I always found the KDE desktop to be perfectly OK in 810.
